Overview
The Cable Matters 402027-BLK is a passive DVI-D to HDMI adapter that connects legacy DVI-D output devices—such as older graphics cards and PCs—to modern HDMI displays. Its compact design features a DVI-D 24-pin male connector on one end and an HDMI female port on the other, allowing you to reuse your existing HDMI cable without extra dongles.
This adapter is a straightforward solution for users who want to bridge DVI and HDMI without spending on an active converter. It supports resolutions up to 1920×1200 at 60 Hz, making it suitable for everyday desktop work, web browsing, and video playback. No external power is required, and the plug-and-play nature means you can set it up in seconds.

Best Use Cases
- Users with legacy graphics cards: If your GPU still has DVI-D ports and you've upgraded to an HDMI-only monitor, this adapter lets you keep using that card without replacing it. Ideal for budget-conscious builds or secondary PCs.
- Dual-monitor setups: Connect a second HDMI monitor to a DVI output on your PC, extending your workspace without buying a new graphics card. Works well for productivity tasks like spreadsheets and coding.
- Home theater PC (HTPC) users: Connect a DVI-output PC to a full-HD TV for streaming movies and YouTube. The 1080p limit matches most HDTV content.
- Not recommended for: Anyone needing 4K output, HDR support, or using DVI-I/DVI-A sources. Also not for users who intend to transmit audio over HDMI—this adapter only passes video (audio requires separate connection or active converter).
